Ivestigation of coagulase-negative staphylococci from infections in surgical patients
Abstract:
All available isolates of coagulase-negative staphylococci from patients admitted to a unit for cardiac surgery during a 14-month period were examined. During this time 382 operations, in 220 of which a prosthetic valve was implanted, were performed. 65 patients suffered 76 episodes of postoperative infection. All coagulase-negative staphylococci isolated were classified by biochemical typing, bacteriophage typing and testing of anitbiotic susceptibility. The results of this investigation were reported and discussed especially from an epidemiological point of view.
Insights
Coagulase-negative staphylococci caused postoperative infections in cardiac surgery patients, particularly those with prosthetic valves. Understanding their epidemiology is crucial for preventing these infections.
Area of Science:
- Medical Microbiology
- Infectious Diseases
- Epidemiology
Background:
- Coagulase-negative staphylococci are significant causes of hospital-acquired infections.
- Cardiac surgery, especially with prosthetic valve implantation, carries a high risk for postoperative infections.
Purpose of the Study:
- To investigate the epidemiology of coagulase-negative staphylococci infections in a cardiac surgery unit.
- To characterize the isolates and identify potential sources of infection.
Main Methods:
- Collection and analysis of all coagulase-negative staphylococci isolates from patients over 14 months.
- Biochemical typing, bacteriophage typing, and antibiotic susceptibility testing.
- Epidemiological analysis of patient data and infection episodes.
Main Results:
- 65 patients experienced 76 episodes of postoperative infection.
- Detailed characterization of coagulase-negative staphylococci isolates was performed.
- The study focused on the epidemiological aspects of these infections.
Conclusions:
- Coagulase-negative staphylococci pose a significant threat in cardiac surgery settings.
- Epidemiological surveillance and characterization are vital for infection control strategies.
- Further investigation into prevention and treatment is warranted.
